LIQUID-DISPENSING APPARATUS.

Specification of Letters Patent. P t t 24,. 2

Application filed March 19, 1920. Serial No. 367,045.

, ments in Liquid-Dispensing Apparatus, of

which the following is a specification.

This invention relates to liquid dispensing systems and has especialreference to gasoline service. stands for conducting gasoline directlyfrom a source of supply to vehicles, such as automobiles.

Objects of our invention are to provide a system for supplying gasolineto vehicles, etc., in a facile and expeditious manner; and to fullyexpel the gasoline from the dispensing hose thereby preventing drippingand the possibility of the purchaser not receiving full measure.

The above principal objects and numerous other co-ordinate objects,which will be apparent from the following specification, are

attained primarily through the instrumentality of compressed aircontrolled by a multiported valve. In this way the apparatus is causedto function without the use of air power machines, gravity operatedmachines, etc. Moreover, the mechanism is simple and neither physical ormental effort of the operator will be necessary, for accurate operationof this device.

The above and other objects and advantages of this invention will be inpart described and in part understood from'the followin description ofthe present preferred embo i'ment, the same being illustrated in theaccompanyin drawings, in which Figure 1 is a, ront elevational View of adispensin stand constructed in accordance with our invention,

Figure 2 is a fragmentary-longitudinal sectional view of the sameshowing the device in connection with a working tank,

Figure 3 is a horizontal sectional view of the valve used in thisinvention, one position of the valve being shown,

Figure 4 is a fragmentary horizontal sectional view of the valve used inour invention and showing a different position of the same, from thatshown in Figure 3.

Figure 5 1s a slmilar view-showing still another position of the valve-Figure 6 is atopdplan viewof the valve with its ca remove Figure i is avertical sectional view through the valve casing showing one position ofthe plug valve in side elevation, and illustrating the valve bearinghanger,

F lgure 8 is a vertical sectional view of the caslng takenon the. line1414 of Fig. 3 showing the valve removed,

Figure 9 is a similar view of the equipped with the valve, and

F lgure 10 1s a side elevational view of the casing valve per se.

In the drawings, a dispensing stand generally designated 12 is providedwhich consists of a base 13, of any desired shape and material, whichhas upstanding thereon a measuring receptacle 14. The receptacle 14 maybe made of transparent material or else provided with a graduatedtransparent panel (not shown). Superimposed on the receptacle 1 1 is acasing 15.

Subjacent the stand 12 is a working tank 16 which has leading thereintoa supply pipe 17, the latter being equipped with a non-return valve 18of any suitable design. The working tank 16 has a liquid pipe 19 leadingupwardly therefrom through the base 13 and terminates in a valve casing20. It will be observed that the supply ipe extends into the workingtank prefera ly to a point in close proximity to the bottom thereandsize and may have mounted therein any' suitable type of multi-portedvalve. In the present instance, however, the valve casing is of aconfiguration designed to receive a plug valve 22. This valve hasportions of its periphery removed to provide a multiported structurewhich communicates with ports in the valve casing, as shown to advantagein Figures 3, 4, 5 and 6, and as will now be explained. Depending fromthe valve 22 through the bottom of the casing 20 is a intle 23, which isengaged by a suitable andle 24., the latter capacitating as a means forrotating the valve. The vpintle extends below the handle and engages abearing arranged on a yielding cross head 23'. Inthe position which thevalve occupies in Fig. 3, the vent ipe 21 is open so that air held inthe wor 'ng tank 16 may be exhausted into an L-shaped passageway 26. Theexhaust first enters the base 26 of the passageway pursuant to which itflows as- 1pe 21 likewise communicates through the main leg and theninto a vent pipe 31. Consequently, gasoline or other liquid in passingthrough the supply pipe 17 into the working tank 16 will cause air inthe latter to be forced throughthe vent ipe 21 and ultimately throughthe pipe 31. he compressed air supply,.which is connected with the valveby a p1pe 28, is cut off while the valve is in this POSItiOII aS is alsocommunication from the discharge port 29. The latter is adapted forcommunication with a poi t in the valve.

1 tion of the valve in which position the compressed air pipe 28 isplaced in direct communication with the vent pipe 21 through f as shownin Fig. 5, is produced by another turn of the handle 24' in whichposition the measuring tank is placed in direct communication with thesource of air supply by connectlng pipes 28 and .27 through a port, 33in the valve. The air flows from the pipe 27 into a passageway 37 iiithe top of the meas: ,urlng tank and thence impinges a float 'in themeasuring receptacle. The liquid rack I will in this-way be forced fromthe meas-' uring tank through jthe discharge port 29 into the valve port30 and thence through the discharge nozzle 34. During this cycle ofoperation the working tank 16 is' vented through the pipe 21, port 32and vent pipe A 31 permittingthe working tank to receive a supply ofliquid simultaneously with the dlspensing of the contents of'themeasuring chamber.

After the valve is successively operated through the cycles of movementab'ove enumerated the handle 24 is returned to the position shown inFigure 3; successive operations of the device may be conducted in thisway,

The: float 35 is movablymounted in ,the measuring tank 14 and is guidedin its movement by the pipes 27 and 31 which extend through suitableopenings in the float. A ar' 36 extends upwardly from said float andinto the casing 15. The bottom of the casing serves as the top of thereceptacle 4 14 and is provided with the passage-way 37 WhlChcommunicates with the vent tube 27. Conse uently when the measuring tankhas bee fi led, and the float is in its uppermost position,communication through the pasgure 4 shows the second cycle ofoperasage-way 37 will be closed, thereby preventing liquid fromflowing-thereinto.

In operation assumingthe valve to be in the position shown iii-Fig. 3"ofthe drawings, in which position the float 35 is in the bottom of themeasuring tank closing communication through the opening 29. Fur-.

the measuring receptacle, under the infiu-.

ence of the compressed air which is admitted through the pipe 28. Duringthis cycle of operation of the valve, the float 35 rises until its-upperface closes the opening into the passageway 37 thus preventing thepassage of air and liquid therethrough.

Moreover, in this way the measuring receptacle will always contain adefinite amount of liquid when filled. The handle 24 is then moved inthe opposite direction rotating'the valve into the position shown inFig. 5, in

whichposition, the gasoline is caused to be dispensed from the measuringreceptacle through the discharge hose 34, 'When the liquid is beingdischarged from the measuring receptacle, the float sinks until itslower face closes the opening 29 thus preventing the passage of anycompressed air therethrough, after the measuring receptacle has beenemptied. After dispensing the desired quantity of gasoline from themeasuring receptacle, which may or may not be the complete contentsthereof, the handle 24is ,returned to the position shown in Fig. 3 ofthe drawings thereby cutting off the flow from the measuring receptacleand lmmediatelyv establishing communication between the top'of saidmeasuring receptacle and the discharge hose 34 so as to. permit theexpansive force of the air remainnig in said measuring chamber toquickly blow out the-liquid contained in the discharge hose, thusemptying it completely and preventing any dri therefrom. 1

t will be understood that the above description and accompanyingdrawings comprehend only the general and preferred embodiment of ourinvention, and that various minor changes in details of construction,proportion and arrangement of parts may be made within the scope of theappended claims without-sacrificing any of the advanta es of ourinvention.

aving thus fully described our invention, what we claim as new anddesire to se cure by Letters Patent, is

1. A liquid dispensing apparatus including a working tank and measuringreceptacle in communication with one another, a.

source of air supply also in communication with the tank and receptacle.a discharge hose connected with the measuring tank, and a single valveto control the filling and discharge of the tank and receptacle, onecycle of operation of the valve causing discharge of the liquid throughsaid discharge hose, a successive operation of the valve permitting thepassage of air through said discharge hose for completely expellingliquid therefrom. 1

2. A liquid dispensing system including a measuring receptacle toreceive liquid and equipped with a float operable under pressure of theliquid when the latter enters the receptacle, air conduits arranged insaid receptacle and extended through the float to guide the movement ofthe latter, said c0nduits conducting air from the receptacle upon risingmovement of the float, and said float being operated downwardly in thereceptacle, for dispensing the liquid, under influence of air forcedthrough said air conduits.

In testimony whereof, we aflix our signatures 1n the presence of twowitnesses.
